Where it applies
Jobs this tool actually does, and the surface each one is exercised on.
Discover what methods a gRPC service exposes when there is no documentation.
coding-agent
The single most useful gRPC tool for an agent. Server reflection means it can enumerate an unknown service's whole interface and call it, with no build step at all.
Call one gRPC method to check behaviour without generating a client.
